Available in PDF, EPUB and Kindle. Book excerpt: Nous décrivons l'utilisation de matrices polymères aux propriétés inhabituelles dans des composites à fibres de verre longues et dans des composites tout organique. Les vitrimères récemment découverts au laboratoire Matière Molle et Chimie une nouvelle classe de polymères. Ils sont réticulés et insoluble comme les thermodurs mais pourtant malléables à chaud, soudables sans apport de matière et recyclables comme les thermoplastiques. Cette propriété de soudage est elle conservée pour un matériau composite à matrice vitrimère renforcé à 50vol.% ? Nous analysons quantitativement et statistiquement les forces de rupture de joints soudés à chaud de façon autogène et comparons à cet effet le composite à matrice vitrimère aux composites classiques. Nous démontrons que seule la matrice vitrimère permet de multiples soudures efficaces grâce aux réactions d'échange qui permettent la formation de liens covalents et la diminution de la rugosité à l'interface. Cette technologie pourrait permettre le remplacement des joints mécaniques ou des adhésifs. Nous explorons aussi un système composite constitué d'un tissu de fibres longues et d'une matrice basée sur des thermoplastiques semi-cristallins à base de polyamides supramoléculaires développés au laboratoire Matière Molle et Chimie. Leur très faible viscosité au dessus du point de fusion est un grand atout vers des méthodes de mise en œuvre et de recyclage améliorées. Nous montrons qu'il est possible de recouvrer les fibres intactes et lavées ainsi que la matrice grâce à un traitement thermique sous pression dans l'eau. Enfin, nous réalisons un bilame vitrimère qui peut être utilisé comme actuateur.

Available in PDF, EPUB and Kindle. Book excerpt: Some years ago in Paisley (Scotland) the International Conference on Composite Materials, headed by Professor I. Marshall, took place. During the conference, I presented a paper on the manufacturing and properties of the Soviet Union's composite materials. Soviet industry had made great achievements in the manufacturing of composite materials for aerospace and rocket applications. For example, the fraction of composites (predominantly carbon fibre reinforced plastics) in the large passenger aircrafts Tu-204 and 11-86 is 12-15% of the structure weight. The percentage by weight share of composites in military aircraft is greater and the fraction of composites (organic fibre reinforced plastics) used in military helicopters exceeds a half of the total structure weight. The nose parts of most rockets are produced in carbon-carbon materials. In the Soviet spacecraft 'Buran' many fuselage tubes are made of boron-aluminium composites. Carbon-aluminium is used for space mirrors and gas turbine blades. These are just a few examples of applications. Many participants at the Paisley conference suggested that the substantial Soviet experience in the field of composite materials should be distilled and presented in the form of a comprehensive reference publication. So the idea of the preparation and publication of a six volume work Soviet Advanced Composites Technology, edited by Academician J. Fridlyander and Professor I. Marshall, was born.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans cette étude, les matériaux composites poly 3-hydroxybutyrate-co-4-hydroxybutyrate (P34HB) / fibres de bambou et polybutylène succinate (PBS) / fibres de bambou ont été préparés en utilisant le mélangeur interne et le moulage par compression. Les propriétés thermo-mécaniques de P34HB et de PBS ont été caractérisées. Les fibres de bambou ont été modifiées par des traitements chimiques. Les propriétés mécaniques telles que la résistance à la traction, la résistance à la flexion, le module d'élasticité et les propriétés thermiques ont été étudiées. Pour les deux types de composites (P34HB et PBS), le module est significativement amélioré, cependant, la résistance du composite est légèrement diminuée. L'allongement à la rupture est plus faible que celui des polymères purs, ce qui indiquerait une bonne adhérence entre la matrice et les fibres. L'étude révèle que l'adhésion est améliorée avec les fibres modifiées avec le silane et l'acide acétique, ce qui entraîne une augmentation des propriétés mécaniques du matériau, par rapport à celles des composites renforcés avec des fibres non traitées. En outre, le taux de 20% de fibres est considéré comme la bonne composition de fibres pour garantir de bonnes propriétés thermo-mécaniques et une absorption d'eau faible.En étudiant ces matériaux composites, nous visons à produire des matériaux respectueux de l'environnement. De plus, l'abondance des fibres de bambou permettra de réduire le coût de la matière première. Ce travail porte principalement sur la modification des fibres de bambou afin d'améliorer les propriétés globales des composites et sur la comparaison de ces propriétés par rapport à celles des fibres non traitées. Pour atteindre une meilleure adhérence matrice-fibre, un agent de couplage et/ou compatibilisant peuvent être étudiés et utilisés dans une future étude.

This book was released on 2012-07-10 with total page 955 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third volume of this six-volume compendium provides methodologies and lessons learned for the design, analysis, manufacture, and field support of fiber-reinforced, polymeric-matrix composite structures. It also provides guidance on material and process specifications and procedures for using the data that is presented in Volume 2. The information provided is consistent with the guidance provided in Volume 1, and is an extensive compilation of the current knowledge and experiences of engineers and scientists from industry, government, and academia who are active in composites. The Composite Materials Handbook, referred to by industry groups as CMH-17, is a six-volume engineering reference tool that contains over 1,000 records of the latest test data for polymer matrix, metal matrix, ceramic matrix, and structural sandwich composites. CMH-17 provides information and guidance necessary to design and fabricate end items from composite materials. It includes properties of composite materials that meet specific data requirements as well as guidelines for design, analysis, material selection, manufacturing, quality control, and repair. The primary purpose of the handbook is to standardize engineering methodologies related to testing, data reduction, and reporting of property data for current and emerging composite materials. It is used by engineers worldwide in designing and fabricating products made from composite materials.
Download or read book Manufacturing of Polymer Composites written by B. Tomas Astrom and published by Routledge. This book was released on 2018-04-27 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential application areas for polymer composites are vast. While techniques and methodologies for composites design are relatively well established, the knowledge and understanding of post-design issues lag far behind. This leads to designs and eventually composites with disappointing properties and unnecessarily high cost, thus impeding a wider industrial acceptance of polymer composites. Manufacturing of Polymer Composites completely covers pre- and post-design issues. While the book enables students to become fully comfortable with composites as a possible materials choice, it also provides sufficient knowledge about manufacturing-related issues to permit them to avoid common pitfalls and unmanufacturable designs. The book is a fully comprehensive text covering all commercially significant materials and manufacturing techniques while at the same time discussing areas of research and development that are nearing commercial reality.
